About this item

  • 【Fits Your Vehicle】 Suitable for use on any gasoline 4-stroke engines with 10, 12 or 14mm spark plugs. Tester checks the amount of leakage in an engine cylinder & helps determine the source. Ideal for testing trucks & late model cars where clearance is minimal.
  • 【Easy To Use】Install the hose to the cylinder, the unit to an air supply, calibrate the leak gauge, and connect the unit to the cylinder hose. Diagnosis is made by observing the amount of leakage indicated on the cylinder leakage gauge and listening for leakage at various points of the car system.Designed to detect a variety of common engine faults. including: Worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets.
  • 【Easy To Read】 Convenient dual gauge design allows the compression gauge tool to test the pressure and leak rate of the cylinder under test at the same time. Ranging from 0-100 psi / 0-7 bar and 0-100%(Accuracy: ±0.5%), easy to read 3-inch gauges would spend less time on readings.
  • 【Working Principle Of Leakdown Detector】Once the leakage tester has been connected to one of the cylinders, compressed air (45-100psi) is fed into that particular cylinder through the built in pressure regulator. Diagnosis is made by observing the amount of leakage that is indicated on the cylinder leakage gauge and by listening for leakage at various points of the cars system. Please note: This cylinder leak tester is not suitable for shallow cylinder.
  • 【Package Contents】480mm flexi hose, 10mm and 12mm spark plug adapters, fixed short connector M14(14mm Brass Coated Aluminum Adapter) x 26mm, fixed long connector M16 x 26mm, pressure gauge, cylinder leakage gauge, air regulator, instructions, and carrying case.

The product didn't work till it was modified put air to the gauges would come up but no air would go into the cylinder do to the tool having a check valve going the wrong way so the bleed down gauge showed the same preasure the regulated gsuge does I took it apart removed check valve and it works as it should

I ordered one of these to perform a leak down test on my 2000 Yamaha WR400F. The kit resembles some of the higher end options on the market, however the quality is not there. The air coupling was a little too large for my air line, but I found one to make it work. I am well versed on the different options for air couplings, therefore I know it was something to do with the kit. Secondly, the air line that connects to the cylinder plug port leaked are at the compressed fitting when whenever I moved or changed the orientation of the hose. For the price, it is not a bad unit if you can get past the lack of quality control, but I would not purchase again. The seller/Amazon allowed me to return it for a full refund.
It's me!

Instructions state calibrating set pressure typically occurs around 15-20 psi. This gauge "set" near 100 psi. So out came my long breaker bar. My last worn out gauge would set at 15. Product works well, but I'll buy another gauge just to compare. Accuracy rules when you're making a decision to open an engine.

Used once and the leak down guage is stuck at 60% and won't go any further and when I add anything over 30 psi it pegs the guage past the ending all the way to the other side of 100%. So can't get any readings and it leaks at the guage and fittings. Horrible amd cheap. Save your money!

De excelente calidad. Tan pronto como abrí el empaque se notaba la calidad en el peso del producto. Y facil de usar, rápido que lo utilize encontré la falla del vehículo. Viene con todas las conexiones es muy útil y super económico, lo recomiendo

Works as it should. It diagnosed a burnt valve in minutes. Easy to use and it works every bit as good as the expensive stuff. Great for the novice mechanic.

Needed to replace my name brand leak down tester in a pinch. I mean it's Christmas I didn't have hundreds to spend. I got this tool. Works amazing and more than exceeded my expectations!

A 'must-have' for any poor compression issues; or suspected overheating issues due to possible head gasket failures or engine/head cracks. Tells precisely if leakage is exhaust, coolant, crankcase, or intake related. An affordable price for valuable diagnostic evaluations. Has been used several times with no problems whatsoever.
